bmp3_set_sensor_settings

int8_t bmp3_set_sensor_settings(uint32_t desired_settings, struct bmp3_settings *settings, struct bmp3_dev *dev);

This API sets the power control(pressure enable and temperature enable), over sampling, odr and filter settings in the sensor.

Parameters

[in]	desired_settings	: Variable used to select the settings which are to be set in the sensor.
[in]	settings	: Structure instance of bmp3_settings
[in]	dev	: Structure instance of bmp3_dev.

Note

: Below are the macros to be used by the user for selecting the desired settings. User can do OR operation of these macros for configuring multiple settings.

* ---------------------|----------------------------------------------
* desired_settings     |   Functionality
* ---------------------|----------------------------------------------
* BMP3_SEL_PRESS_EN    |   Enable/Disable pressure.
* BMP3_SEL_TEMP_EN     |   Enable/Disable temperature.
* BMP3_SEL_PRESS_OS    |   Set pressure oversampling.
* BMP3_SEL_TEMP_OS     |   Set temperature oversampling.
* BMP3_SEL_IIR_FILTER  |   Set IIR filter.
* BMP3_SEL_ODR         |   Set ODR.
* BMP3_SEL_OUTPUT_MODE |   Set either open drain or push pull
* BMP3_SEL_LEVEL       |   Set interrupt pad to be active high or low
* BMP3_SEL_LATCH       |   Set interrupt pad to be latched or nonlatched.
* BMP3_SEL_DRDY_EN     |   Map/Unmap the drdy interrupt to interrupt pad.
* BMP3_SEL_I2C_WDT_EN  |   Enable/Disable I2C internal watch dog.
* BMP3_SEL_I2C_WDT     |   Set I2C watch dog timeout delay.
